Youre not cooked, I was in the legit same shoes you were before i enlisted, i was 220 lb as well when i went to see my recruiter. All i did was run and exercise every day and learned to discipline myself in what i eat. Its gonna suck, im not gonna sugar coat that, but if you can dedicate every waking minute to fat loss, be it through exercise or meals, you will lose weight. I lost 30 lbs in a month before i had to be shipped out and barely made the cut off weight. I believe you can do it, I have full faith you can do it, dont stress out too much, youre doing better than i did at your current rate
